What is sidejacking?
"Sidejacking" refers to the use of unauthorized identification credentials to remotely hijack a valid web session in order to take over a specific web server. Typically, sidejacking attacks are carried out through accounts where the user enters their username and password. Sidejacking attacks are used to find an insecure SSL (socket layer) cookie.
Usually, websites where users enter their usernames and passwords are the kind that are flirted with. Websites that use SSL don't have that many chances of fling, but if the webmasters fail to authenticate the website themselves through encryption, the use of SSL can be negated. Unsecured Wi-Fi hotspots are also vulnerable.
Sidejacking uses packet sniffing to steal a cookie and read network traffic. The data sent to the server or the web pages viewed by the victim are recorded so that the perpetrator can steal private information and impersonate the personal benefit of the user.
Many would be surprised to know how easily someone can hijack the websites they are using, especially with open Wi-Fi. Gone are the days when hackers were locked in their homes and carried out their clandestine computer interventions.
Now, a hacker could sit right next to his victim in a coffee shop, library, airport, or anywhere where the user's password on the system could be remembered. Smartphones and laptops in these hotspots should also be used very carefully.
While it is difficult to prove that someone has been accessed in an unauthorized manner on a password-protected site, in the United States that person has been charged with a misdemeanor. If there is more than 1,000 $ damage, the offense is considered a crime.
Computer experts suggest that when using Wi-Fi, you should use a virtual private network that uses a security tunnel that fraudsters cannot access.
